SLC52A3

Solute carrier family 52 (riboflavin transporter), member 3, formerly known as chromosome 20 open reading frame 54 and riboflavin transporter 2, is a protein that in humans is encoded by the SLC52A3 gene.

Function

This locus likely encodes a transmembrane protein that may function as a riboflavin transporter.

Clinical significance

Mutations at this locus have been associated with Fazio–Londe disease and Brown-Vialetto-Van Laere syndrome.
